The Relation of Preoperative HbA1c Level With Intraoperative and Postoperative Complications in Type-2 Diabetic Patients: An Observational Study.

Background Perioperative dysglycemia increases morbidity and mortality, particularly among those with diabetes mellitus (DM), and elevated HbA1c levels, reflecting long-term blood glucose, are linked to poor healing and higher infection rates. This study investigates the link between preoperative HbA1c levels and perioperative outcomes in type-2 DM patients. Methodology This prospective observational study was conducted in India between January 2021 and April 2022. Sixty patients aged 18-60 with type-2 DM who underwent elective surgery under general anesthesia (GA) were included; the American Society of Anesthesiologists class >III and patients with severe organ failures were excluded. Participants were divided into two groups: A (HbA1c ≤7.5%) and B (HbA1c >7.5%). Data on preoperative vitals, intraoperative hemodynamics, and postoperative complications were collected. SPSS v23 was used for data analysis; p-value <0.05 was considered significant. Results The mean age of the participants was 48.22 years; males comprised 58.3%. Group A had a higher proportion of oral hypoglycemic agents. Group B showed higher maximum mean blood pressure and intraoperative blood sugar levels at one hour. Postoperatively, Group B had higher glucose levels, more prevalent hyperglycemia, and higher preoperative and postoperative blood urea levels. No significant differences were found in postoperative outcomes like acute kidney injury (AKI), leukocytopenia, leucocytosis, fever, and intensive care admission. Surgical site infection (SSI) incidence was higher in group B, though not statistically significant. Group B had more extended hospital stays. Conclusion Preoperative HbA1c above 7.5% was associated with impaired perioperative glycemic control and higher dysglycemic episodes. Higher preoperative HbA1c was found to be linked to increased postoperative hyperglycemia, AKI, intensive care admissions, and more extended hospital stays, though not statistically significant. SSI incidence was higher, highlighting its importance over preoperative HbA1c.

Effect of Sevoflurane, Isoflurane, and Desflurane on the Random Blood Glucose Levels in Non-diabetic Patients Undergoing General Anesthesia: A Randomized, Single-Blind Study.

BACKGROUND: Volatile anesthetic agents like sevoflurane, isoflurane, and desflurane are widely used for maintaining general anesthesia (GA). Their effect on the autonomic system is different and can impact the blood sugar homeostasis. This study compares the intraoperative blood glucose levels in non-diabetic patients undergoing non-cardiac surgery under GA with the three volatile agents. METHODS: A randomized, single-blind, parallel-arm study recruited 105 non-diabetic patients into three groups. GA induction and maintenance were standardized except for the volatile agent. Capillary blood sugar levels were measured at different time points and compared between and within the groups. A p-value of <0.05 was considered significant. RESULTS: Entire participants completed the study, and their baseline characteristics were statistically indifferent. Intraoperative blood glucose rise and variation were the highest in the desflurane group and the lowest in the isoflurane group; the differences were statistically significant at 15, 30, and 45 minutes. The highest blood sugar level was noted at 60 minutes in all groups; after that, the level started falling. However, none of the raises were beyond 140 mg% to categorize them as hyperglycemia. CONCLUSION: Intraoperative glycemic variation was evident with isoflurane, sevoflurane, and desflurane. The maximum increase from the pre-induction level was noted at 60 minutes. However, none of the readings reached the hyperglycemia level. The rise was significantly higher in desflurane-based anesthesia than in isoflurane. This study was, however, conducted in non-diabetic patients; hence, results might not be extrapolated to diabetic patients.

A Randomized Study Comparing Ultrasound-Guided Internal Jugular Vein Cannulation Using Two Techniques: Short-Axis Out-of-Plane With Dynamic Needle Tip Positioning Versus Long-Axis In-Plane.

Introduction Internal jugular vein (IJV) cannulation is a routine procedure in operating rooms, critical care units, and perioperative settings. Ultrasound guidance has notably increased the success rates of IJV cannulation. A modified ultrasound technique known as the short-axis out-of-plane method with dynamic needle tip positioning (DNTP) allows for continuous visualization of the needle tip throughout the procedure. This study aims to compare the first-pass success rate of IJV cannulation using the DNTP and long-axis in-plane (LAIP) approaches. Methods One hundred patients between 18 and 70 years undergoing elective surgery requiring IJV cannulation were recruited. Patients were assigned randomly to the DNTP group (n = 50) or the LAIP group (n = 50). We recorded the first-pass success rate, time to achieve successful cannulation, number of skin punctures, overall success rate within five minutes, and potential complications such as pneumothorax and hematoma. Results The first pass success rate was higher in the DNTP group (48/50, 96%) as compared to the LAIP group (38/50, 76%, relative risk, 1.67; 95% confidence interval, 0.039-0.707; p = 0.008). The cannulation time was shorter in DNTP (116.98 ± 22.90 seconds) versus the LAIP group (213.04 ± 52.08 seconds; p < 0.001). No complications like pneumothorax or hematoma were noted in both groups. Conclusion We conclude that the ultrasound-guided DNTP technique for IJV cannulation, as compared with the LAIP technique, may significantly improve the first attempt cannulation, number of attempts, and cannulation time.

Radial Arterial Cannulation by Ultrasound-Guided Dynamic Needle-Tip Positioning Using the Short-Axis Out-of-Plane Approach Versus the Long-Axis In-Plane Approach: A Randomized Controlled Study.

Introduction Radial artery cannulation is a commonly performed invasive procedure for assessing a patient's hemodynamic status and collecting blood samples. Ultrasound guidance has shown benefits in improving the success rate of first-attempt cannulation. Two main approaches, short-axis out-of-plane (SAOOP) and long-axis in-plane (LAIP), are commonly used. A modified technique called dynamic needle-tip positioning (DNTP) using the short-axis out-of-plane approach has been reported to enhance arterial catheterization. This study aims to compare the first-attempt success rates of radial artery cannulation using the two techniques, DNTP versus LAIP, along with overall success rates, cannulation time, and number of attempts. Methods This prospective, randomized, controlled, clinical study was conducted after obtaining clearance from the Institute Ethics Committee of AIIMS, Raipur. Ninety-six patients between the ages of 18 and 50 years, undergoing elective surgery under general anesthesia, and required radial arterial cannulation were randomized and equally allocated into two groups as the LAIP and DNTP approaches. The first-pass success rate, time to achieve successful cannulation, number of attempts needed, overall success rate within five minutes, and potential complications, such as thrombosis, vasospasm, and hematoma, were recorded. Results A total of 96 patients were included, with 48 in the LAIP group and 48 in the DNTP group. The DNTP group showed statistically significant advantages over the LAIP group, with a higher first-pass success rate (97.9% vs. 83.3%; p = 0.014) and shorter time to achieve successful cannulation (9.29±3.79 vs. 26.16±20.22 seconds; p = 0.001). Conclusion The ultrasound-guided short-axis DNTP technique for radial artery cannulation demonstrated a significant advantage as compared to the LAIP technique. The DNTP technique resulted in higher first-attempt cannulation success and shorter cannulation time.

Atracurium Versus Cis-Atracurium for Laryngeal Relaxation and Hemodynamic Stability in Pediatric Patients: A Randomized, Double-Blind Study.

Background and aim Equipotent dose of atracurium and cis-atracurium has failed to show clinically equi-effective muscle relaxation actions required for laryngoscopy and endotracheal intubation (LETI) in adults. There needs to be more data on children. We aimed to compare the efficacy of equipotent atracurium and cis-atracurium for producing optimal LETI. We also compared the hemodynamic stability and side effects. Methods With approvals and informed consent, 104 children between three and 12 years were enrolled in the present randomized, double-blind, parallel-arm study. Fifty-two participants were recruited in each group and received either 2ED95 atracurium (0.5mg/kg) or 2ED95 cis-atracurium (0.1mg/kg). Three-point scale, i.e., excellent, good, and poor, were assigned based on jaw relaxation, vocal cords, diaphragmatic movement, coughing, and resistance to the laryngoscope blade. Basic hemodynamics and adverse events like flushing, hemodynamic instability, and airway spasms were noted. The groups were compared using Wilcoxon-Mann-Whitney U or Chi-square tests as applicable; a p-value <0.05 was considered significant. Results Entire enrolled participants completed the study. Excellent LETI conditions were significantly higher in the atracurium than in cis-atracurium (53.8% versus 19.2%, p-value <0.001). In the present study, blunted laryngoscopy-related sympathetic surge containing the increase in hemodynamic parameters within 20% from the baseline was noted in both groups, but the blunting and fall back of hemodynamic towards the baseline was rapid in the atracurium (within 7 minutes of LETI) group than cis-atracurium, i.e., 72 minutes; p-value <0.001. Only one flushing was noted in the atracurium group compared to none in the cis-atracurium. Conclusion 2ED95 dose of cis-atracurium (0.1mg/kg), although have minor advantages of maintaining hemodynamic better, has lower adverse events, it provides significantly lower 'Excellent LETI conditions' when compared to 2ED95 dose of atracurium (0.5mg/kg) in children of age three to 12 years.

Aortic pseudo-aneurysm: cause of life-threatening hemoptysis in a 13-month-old child.

Aortic aneurysms and pseudo-aneurysms are a rare occurrence in the pediatric age group. True aneurysms are usually related to infection or to inherited disorders while pseudo-aneurysms occur following trauma or infection. We present a case of a pseudo-aneurysm of the descending thoracic aorta in a 13-month-old child, who presented with life-threatening massive hemoptysis. Though no clear-cut etiologic factor was identified on clinical examination and investigations, presence of neutrophilic infiltration in the wall suggested an infective nature.

Isolated pericardial and intracardiac hydatidosis: presentation as congestive cardiac failure and fatal pulmonary embolism.

Localization of hydatid cysts in the heart is a rare phenomenon, with an incidence of 0.5-2%. In almost half these cases, the heart is the sole organ to be involved. We report a case of massive pericardial hydatidosis in a female patient who presented with features of congestive cardiac failure. Cysts in the endocardium of right side of the heart resulted in fatal pulmonary embolism.

Rhabdomyoma of the right atrium: report of a case.

Rhabdomyomas are the most common primary cardiac tumors in childhood, and are considered to be congenital lesions. They are uncommon in adolescents and adults due to their tendency for spontaneous regression. Majority of them are located in the ventricular chambers, and are also associated with tuberous sclerosis. The indications for surgery include hemodynamic compromise and intractable arrhythmias. We describe a right atrial rhabdomyoma in a previously healthy 16-year-old girl who presented with palpitation and dizziness of recent onset. Postoperative evaluation had not revealed stigmata of tuberous sclerosis.
